Need my old versions of cc back!!

So I am in College with a ton of work to due in Photoshop, Illustrator, Premiere, and Aftereffects. I am still running windows 7 and have the CC2018 and 2015 versions of the above mentioned software. Its finals this week and I have two jobs. I have no time to rebuild my O.S. Last week something happened an my computer started to have issues linking to the servers. That issue has been resolved. Unfortunatly in the process the tech had me run the clean up tool. So my old software version are gone. So I did a restore to a previous date and then did the fixes that allowed me to sync back to adobeCC. The apps are broken now though even though I did a restore. I have another computer also. On this one I did not run the clean up and applied the fixes and my old versions work fine. Unfortunatly that computer only has one program I need and is a piece of junk. Please help me repair my old adobe software.
